利用钻井岩心、测井及地震资料,对黄骅坳陷孔南地区孔店组孔一下亚段进行岩石学、测井响应及地震反射特征的综合研究,识别出4种岩相组合、4种测井相类型和3种地震相类型;划分出扇中和扇端亚相;建立了冲积扇的垂向沉积序列并探讨了冲积扇的空间展布规律。认为研究区孔一下亚段陡坡带属于干旱气候条件下发育的进积型冲积扇沉积体系类型。冲积扇的研究是孔二段到孔一段古环境变化、古构造及盆地演化的重要证据。
Based on the drilling core, well logging and seismic data, a comprehensive study on the petrology, well logging response and seismic reflection characteristics of the Kongdian Formation Kongonan Formation in the Kongnan area of Huanghua Depression has been carried out. Four lithofacies assemblages and four types of measurements Well facies type and three types of seismic facies. The mid-fan and fan-end subfacies were divided. The vertical sedimentary sequence of alluvial fan was established and the spatial distribution of alluvial fan was discussed. It is concluded that the steep slope of the sub-subsurface in the study area belongs to the type of sedimentary system of progressive-type alluvial fan developed under arid climatic conditions. The study of alluvial fans is an important evidence that paleoenvironmental changes, palaeo-tectonics and basin evolution from the second member to the first member of Konggong Formation.
